Bug ID: 356884
Summary: kscreen messes with original xrandr config, does not
respect saved config, and apply defined config only on
the second try.
Product: plasmashell
Version: master
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: Multi-screen support
Assignee: aleix...@kde.org
Reporter: luizl...@gmail.com
CC: plasma-b...@kde.org
Hello,
Since some days (weeks?) kscreen is messing with my display on login and I'm
unable to fix it with kde.
I'm using opensuse buildservice packages:
plasma5-desktop-5.5.90git~20151215T210835~93e437c-11.1.x86_64
kscreen5-5.5.90git~20151129T090237~7a8a41d-1.1.x86_64
At login screen, everything is like I want. I just removed kscreen config.

loginscreen-xrandr.txt
After login, during splash, kde is OK. Just after the splash closes, kscreen
seems to start to mess the screen. The result is one screen over the over.
Rotation is ok, the bigger screen is using a lower res and the other one is
using the last resolution (but not the biggest one). Plasma crashed and I left
it closed (it has its own bunch of bugs related to screen reconfiguration).
postlogin_auto-kscreen.conf

postlogin_auto-xrandr.txt
Now I changed it using kscreen to what I wanted. However, the result config in
xrandr does not match what I see in kscreen. There is a space between screens.
If I exit kscreen config and come back, the visual feedback in kscreen matches
the current config (snapshot2).

Once again, I redo the config in kscreen. Now I get what I wanted. Kscreen
feedback matches the config.
postconf2-kscreen.conf

However, this setup does not survive a reboot. It goes back to what kscreen
autoconfigure in postlogin_auto*
postrelogin_kscreen.conf
postrelogin-snapshot.png (with plasma)
postrelogin_xrandr.txt
And I need to go all over again the double config...
Now about plasma:
After the login, it matches how the screen is configure. After the first it is
still OK. However it got confused after the second config. In screenshot,
konsole and kscreen-config are maximized, one on each screen. kde launcher
shown is from the right screen.

Killing plasma fixes the window sizes instantaneusly. If relaunched, it get the
correct config.
In summary, I have on every login to reconfigure kscreen twice and restart
plasmashell.
Reproducible: Always
